Abbrev.
The detection of a block leaving a particular state and when it
returns back to that state.
One of the standard function blocks defined by the Fieldbus
AO
Foundation.
A software program that interacts with blocks, events and
objects. One application may interface with other applications
or contain more than one application.
A logical software unit that makes up one named copy of a
block and the associated parameters its block type specifies.
It can be a resource block, transducer block or a function
block.
A step-in system design: selecting functional units,
assigning their locations and identifiers, and defining their
interconnections.
A physical entity capable of performing one or more specific
functions. Examples include transmitters, actuators, control-
lers, operator interfaces.
DD Description of FBAPs within a device.
A standardized programming language (similar to C) used to
DDL
write device descriptions.
User-defined identifier for device.
An instantaneous occurrence that is significant to scheduling
block execution and to the operational (event) view of the
application.
Communications protocol for a digital, serial, two-way
FF system that interconnects industrial field equipment such as
sensors, actuators and controllers.
An executable software object that performs a specific task,
FB such as measurement or control, with inputs and outputs
that connect to other entities in a standard way.
The part of the device software that executes the function
FBAP
blocks (PID, AO, transducer, or resource blocks).
A device which is responsible for keeping a link operational.
LAS The LAS executes the link schedule, circulates tokens, distrib-
utes time messages and probes for new devices.
The least common multiple of all the loop times on a given
link.
A term used to describe signal processing in a device that is
MSP
not defined by FF specifications.
